In October of this year, we will have several Green comets Cross the sky in the middle of a beautiful color show. Two of them will require us to arm ourselves with a prismatic or telescope in order to look for them. However, we can see another naked eye. Just look at the western sky to find this green ball fringing the sky.
All of them are green comets that were discovered In the same yearThe field, however, still have not seen them Enlightened enough So that we can watch them.
It was necessary that they would approach the ground and the sun in order to acquire their characteristic green color, and so that we saw them. Nevertheless, let’s see when and how we can see each of the 3 green comets that come from the road to Earth this month of October 2025.
How are green comets?
In fact, there is no own light in comets. They are nothing more than Pieces of dry ice, water, rocks and other substances, such as ammonia, methane and a little metal This, being very low temperatures, remains frozen. However, when they approach the sun, ice in their core It heats up so much that it evaporatesgiving rise to an atmosphere known as Coma, that from the solar winds spreads back, forming a kind lineWe see them as a field as wrapped in a flame, but in fact these are very hot gases with different types of substances. And where is the warmth entering the game. Depending on what these substances are, they will release some colors or others When excited by solar radiation.
Green comets contain a lot Diana carbonThe field, that is, molecules consisting of two related carbon atoms. When these compounds are excited, they emit Greenish lightTherefore, the more diamonic carbon, the more green the snake will be visible. It will also look greener when its temperature will be larger and, of course, when the sun is closer.
Which of them can we see these days?
The most important of the green comets that the sky crosses in October will become A6 Lemmon. Will reach its point closest to the ground October 21. It will be the perfect time to see it, as it will be quite bright to observe the naked eye. It is true that he will shine even more than November 8, when he reaches his point closest to the sun, but then he moved away from the ground, and we will not see it so clearly. If you want to see it, Look west after the sun.
If you miss this, you have two other options, although You will need binoculars. The first of other green comets is C/2025 R2 SwanWhich was discovered only a few weeks ago, when he went through his point, closest to the sun. In fact, it was so close to the star king that he was not seen from the ground observatory. The opening was carried out in ESwan instrument of the Solar and Heliosphere Observatory NASAThe field of his nearest point on the ground will be October 20So this practically coincides with A6 Lemmon in heaven. In fact, the moment and place will be the same: To the west, at sunset. The only problem, we insist, is that it will not be visible to the naked eye.
Finally we have C/2025 K1 AtlasWhich has become very little bright, but acquires sufficient brightness when it approaches the sun and heats up. You can try to see this with binoculars, although will still shine a little moreIt will reach its maximum point on October 8th. Of course, in this case you should look at the sky at dawn. Do not give up if you do not see it on October 8, possibly brilliant enough for observation for several weeks.
